State of the art

Ensuring the quality of service for users of mobile terminals is a very important task for network service providers. Knowing the experience of using their services, the network service provider can accordingly develop an optimized strategy and adjust the configuration of resources in order to make the services attractive to more users and constantly improve the performance of the network service provider. In addition, a network service provider can effectively compare and analyze in accordance with the competitive environment in order to have an idea of its place in the competition, as well as know its own weaknesses and weaknesses of competitors in order to increase its competitiveness and take advantage of the weaknesses of competitors to achieve a competitive advantage.

A network management system based on a standard quality of service control mode can only control the quality of service of a medium-sized network element of a network backbone device, such as a radio network (CP) (RAN) side, a core network, or a gateway side. Therefore, a sounding solution is proposed in the prior art. As part of this solution, interfaces such as Iu-Ps, Gb, Gn, Gi and Gw are monitored using the sensing systems of the CP side, the core network side and the operational gateway side, and it is possible to control the experience of using network services of users of the whole network. However, this solution is limited to the quality control of wireless network services in the area that connects the base station with the Internet, and does not allow to control the basic quality indicator (QQI) in the area from the base station to the user of the mobile terminal.

Therefore, the study of the quality of functioning of wireless services, in particular the precise control of the user experience of a mobile user in the field of quality of Internet access services, is a technical task that urgently needs to be solved in relation to wireless operations.

Description of Embodiments

In order to give those skilled in the art a better idea of the solutions proposed by the embodiments of the present invention, these embodiments of the present invention will now be described in detail with reference to the attached drawings and implementation methods.

According to a method and apparatus for monitoring the quality of Internet access services for a mobile terminal, in embodiments of the present invention, by installing a deep packet inspection (DPI) technology on the side of the mobile terminal, the mobile terminal is configured to collect an IP packet of Internet services access, perform identification and verification of the IP-data packet, collect statistics on the basic quality indicator (POC) of the Internet access service of the mobile terminal side according to the results Tattoos verify and load SSV obtained by statistical data on a network server to a network server controlled by the quality of Internet access services for a mobile terminal in accordance with the basic quality indicator, thereby effecting accurate control of the quality of a mobile terminal network.

FIG. 1 is a flowchart of a method for monitoring the quality of Internet access services for a mobile terminal according to an embodiment of the present invention, where the method includes the following steps.

Step 101: the mobile terminal collects the IP data packet of the Internet access service.

Since the data transfer route of the telephony services and the data transfer route of the Internet access services are separated, and the IP data packet of the Internet access services has a fixed transmission path, the IP data packet of the Internet access services can be obtained by using the transmission path. The four-level structure of a standard TCP / IP network includes a network interface layer, an Internet layer, a transmission layer, and an application layer, as shown in FIG. 2. The IP data packet is located at the Internet level. In an embodiment of the present invention, in one implementation method, at the Internet level of a four-layer TCP / IP model, an IP data packet can be assembled and the resulting IP data packet can be cached for later identification and verification. In another implementation method, an Internet level IP data packet is filtered based on a port of Internet access services. For example, a mobile terminal launches two Internet access services - a QQ client and viewing HTTP web resources; the mobile phone can detect a port range corresponding to the process corresponding to the QQ client in order to isolate all streams belonging to the QQ client at the Internet level, where the remaining packet of IP data at the Internet level belongs to the viewing of HTTP web resources.

Step 102: the mobile terminal identifies the type of Internet access service corresponding to the IP data packet.

Each Internet access service has a corresponding characteristic. Therefore, in an embodiment of the present invention, the IP data packet can be identified by a variety of different identification methods, for example, such as port identification, feature identification, and ratio identification, to identify the type of Internet access service of the five-part stream in the IP data packet. The methods will be described separately with reference to examples. To identify the type of Internet access service corresponding to the IP data packet, any or several of three methods of identification can be used: port identification, characteristic identification and ratio identification.

1. Port Identification

For some protocols provided by standard protocol specifications, authentication can be performed using a known port.

For example, for a protocol, a domain name system (DNS) can be authenticated using the well-known port 53 of the DNS.

2. Characterization

Many protocol message packages include specific keywords, and these keywords can be placed in a fixed position or in a variable position. These keywords form the content characteristic of protocol message packets.

For example, an HTTP (Hypertext Transport Protocol) message packet includes keywords such as GET, POST, HTTP1 / 1, and HOST. If these keywords included in the IP data packet are identified, it can be determined that the type of Internet access service corresponding to the IP data packet is an HTTP web resource viewing service.

3. Identification of the ratio

For some services, the control flow and the service flow are separate, and the service flow has no characteristic. In this case, a ratio identification technology may be used. In particular, a control stream may first be identified; in relation to the control stream, in-depth packet inspection can be performed according to the control stream protocol; then the corresponding service flow is identified based on the protocol content (IP information and port).

For example, for an FTP file transfer service (file transfer protocol), the FTP interaction control flow is first identified; then, the accompanying characteristic information (IP and port) of this data stream is obtained by checking the FTP control stream; and then the FTP data stream is identified using the characteristic information.

Of course, when put into practice, the type of service corresponding to the IP data packet can be identified both by a single identification method and comprehensively by a multitude of identification methods.

For example, the standard port for the HTTP Web Resources Viewer service is (80, 8080). Therefore, the service for viewing HTTP web resources can be identified using the port and selecting a method for requesting the name of the method defined by the HTTP protocol, such as GET, POST or PUT, and the information field according to HTTP version (HTTP / 0.9, HTTP / 1.0 or HTTP / 1.1). Another example: for the FTP file transfer service, based on the FTP protocol, the FTP file transfer service can be identified by identifying a standard radiation pattern, such as 220/226, and port characteristics.

For various types of Internet access services, the identification of an accompanying protocol message requires a deep packet inspection (GUI) (DPI); in addition, in some cases, it is necessary to further determine whether some related protocol messages belong to the same web page. Whether the messages “Get request”, “200 OK” and “Data.n” belong to the same web page can be determined on the basis of the “five”, that is, all the flows of one web page are determined on the basis of the “five”.

The identification process mentioned above includes mainly surface identification of the L3 / L4 protocol, deep identification of the L7 / L7 + protocol, etc.

Step 103: the mobile terminal performs in-depth packet inspection for the IP data packet to obtain a verification result.

Step 104: the mobile terminal collects statistics on an indicator of the basic quality of Internet access services corresponding to the type of Internet access services according to the result of checking the IP data packet.

Since Internet access services can have many different types of services, such as the HTTP web resource viewing service, the WAP service (wireless application protocol), the FTP service, the DNS service, and the TCP service (transmission control protocol), the statistics for different Internet access services are data on the corresponding indicator of basic quality can be collected according to the result of checking the IP packet of the service.

For example, for an HTTP web resource viewer service or a WAP service, the network layer IP data packet of an HTTP web resource viewer or a WAP service can be checked to determine if a network layer IP packet data packet includes a message representing the following event: HTTPHomePageRequest event , the HTTPHomePageResponse event, the HTTPGet event, the HTTPFail event, the HTTPDataTransferStart event, and the HTTPDataTransferComplete event. The result of the verification may include one or more of the events mentioned above.

According to the events mentioned above, statistics can be collected on one or more indicators of these services, such as the percentage of successful attempts to respond to the home page, the duration of the response of the home page, the percentage of successful attempts to refresh the page, the duration of the page refresh, and page load speed. In particular, statistics can be collected on the percentage of successful attempts to respond to the start page and the response time of the start page of the Internet access service according to the HTTPHomePageRequest event and the HTTPHomePageResponse event over a given period of time; statistics can be collected on the percentage of successful page refresh attempts according to the HTTPGet event and the HTTPFail event over a specified period of time; and statistics on page refresh duration and download speed can be collected according to the HTTPDataTransferStart event and the HTTPDataTransferComplete event.

For the FTP service, the FTP service network layer IP data packet can be checked to determine if the network layer IP packet data includes a message representing the following event: FTPConnectionRequest event, FTPConnectionResponse event, FTPULDataTransferStart event, FTPULDataTransferComplete event, FTPULFirstDataPacket event, FTPULLastDataP event , the FTPDLDataTransferStart event, the FTPDLDataTransferComplete event, the FTPDLFirstDataPacket event, and the FTPDLLastDataPacket event. The result of the verification may include one or more of the events mentioned above.

According to the events mentioned above, statistics can be collected on one or more indicators of the FTP service, such as the percentage of successful attempts to establish a connection, the duration of the connection, the average download speed to the main system and the average download speed from the main system. In particular, statistics can be collected on the percentage of successful connection attempts and the duration of the FTP service connection establishment according to the FTPConnectionRequest event and the FTPConnectionResponse event over a given period of time; statistics can be collected on the average download speed to the main FTP service system according to the FTPULDataTransferStart event, FTPULDataTransferComplete event, FTPULFirstDataPacket event and FTPULLastDataPacket event; and statistics can be collected on the average download speed from the host system according to the FTPDLDataTransferStart event, FTPDLDataTransferComplete event, FTPDLFirstDataPacket event, and FTPDLLastDataPacket event.

For a DNS service, an FTP service network layer IP data packet can be checked to determine if a network layer IP packet data includes a message representing the following event: DNSResponse event or DNSQuery event. According to the DNSQuery event and the DNSResponse event for a predetermined period of time, statistics can be collected on the percentage of successful DNS service check attempts and / or DNS service check delay.

For a TCP service, a TCP network layer IP data packet can be checked to determine if a network layer IP packet data includes a message representing the following event: TCPYAttempt event or TCP_ASK event. According to the TCPYAttempt event and the TCP_ASK event for a predetermined period of time, statistics can be collected on the percentage of successful attempts to establish a TCP service and / or delay in establishing a TCP service.

In particular, after identifying the service type of the IP data packet service, the corresponding Internet access service is checked according to the standard service type protocol format, including checking the L7 / L7 + protocol, etc.

For example, the HTTP web resource viewing service allows a specific method and response, such as Get and 200 OK, corresponding to the contents of each field of the first line (First line) according to the HTTP protocol standard, to determine if the connection request to the web page was successful; and a QoS indicator is recorded, such as a point in time, statistical duration and page loading speed corresponding to each request-response event. A specific process will be presented in detail below as an example.

For the WAP 1.X Internet access service, the request and response fields, such as Get and 200 OK, can be identified by checking according to the standard WAP protocol, the TYPE PDU and STATUS fields to determine whether the connection request to the web page was successful; and a QoS indicator is recorded, such as a point in time, statistical duration and page loading speed corresponding to each request-response event.

For the FTP file transfer service according to the standard FTP protocol, a connection request field, such as SYN / SYN and ACK / ASK, and a response field, respectively using 220/226 as a label, can be checked to determine if the FTP connection is successful and whether it has completed file transfer; SIZE field can be checked to get file size; and a key quality indicator (QoS) is recorded, such as a point in time, statistical duration and file transfer size corresponding to each request-response event.

For the DNS service, the DNS Query and DNS Response fields and corresponding time points can be checked; and statistics are collected on the percentage of successful attempts and the delay according to the result of the response.

For the TCP service for collecting statistics on the success rate and delay, the tripartite representation of TCP SYN Attempt, TCP SYN ACK and ACK, and corresponding time points can be checked.

The specific process for collecting statistics on the core quality indicator for various services will be described below.

Step 105: the mobile terminal uploads the primary quality metric obtained using the statistical data to the network server so that the network server controls the quality of the Internet access service for the mobile terminal according to the primary quality metric.

It should be noted that when applied in practice for different types of Internet access services, statistical data can be collected for different types of indicators. The types of indicators mentioned above for various Internet access services are illustrative only and can be specifically determined according to the application requirements, and are not limited to the embodiment of the present invention.

Additionally, the process of uploading a key quality metric obtained using statistical data to a network server can be performed immediately after collecting statistical data or periodically. In addition, after turning on the mobile terminal, the corresponding application for controlling the Internet access service for the mobile terminal can be launched. After the discovery of the Internet access service, statistics are collected on the indicator of the basic quality of the Internet access service according to the above procedure, and the result of the statistical data is downloaded to the network server. Of course, the selection function may also be provided to the user to determine whether to launch the above-mentioned application to control the Internet access service for the mobile terminal. This is not limited to an embodiment of the present invention.

Therefore, according to the method for monitoring the quality of Internet access services for a mobile terminal provided by an embodiment of the present invention, the mobile terminal collects a packet of IP service data; identifies the type of Internet access service corresponding to the IP data packet; Performs in-depth packet inspection for an IP data packet collects statistical data on the indicator of the basic quality of the Internet access service according to the result of checking the IP data packet; and uploads the basic quality indicator obtained by statistics to the network server, so that the network server controls the quality of the Internet access service for the mobile terminal according to the basic quality indicator, thereby accurately monitoring the network quality for the mobile terminal and providing the basis for accurate decision making on network optimization.

In order to further improve network performance and network-side maintenance capabilities to provide the basis for accurate decision making on network optimization, in another embodiment of the present invention, a monitoring strategy may be further developed on the network side.

FIG. 3 is another flowchart of a method for monitoring the quality of Internet access services for a mobile terminal according to an embodiment of the present invention, the method including the following steps.

Step 201: the mobile terminal receives a control strategy from a network server, the control strategy being used to indicate the type of Internet access service that needs to be monitored, and an indicator of the basic quality of the service corresponding to the type of Internet access service.

Step 202: the mobile terminal collects the IP data packet of the Internet access service.

Step 203: the mobile terminal identifies the type of Internet access service corresponding to the IP data packet.

Step 204: the mobile terminal determines, according to the control strategy and the type of Internet access service, the corresponding IP data packet, whether to analyze the basic quality indicator of the Internet access service; and if it is determined that the analysis of the indicator of the main quality of the Internet access service should be carried out, proceeds to step 205, otherwise it proceeds to step 208.

Step 205: the mobile terminal performs in-depth packet inspection for the IP data packet to obtain a verification result.

Step 206: the mobile terminal collects statistics on a basic quality indicator of the Internet access service corresponding to the type of the Internet access service according to the result of checking the IP data packet.

Step 207: the mobile terminal uploads the primary quality metric obtained using the statistical data to the network server so that the network server controls the quality of the Internet access service for the mobile terminal according to the primary quality metric.

Step 208: the mobile terminal deletes the IP data packet.

It should be noted that the above step 201 may be performed when the mobile terminal is turned on, or after receiving an updated notification to the network side. If the control strategy is locally stored by the mobile terminal, after receiving a new control strategy from the network server, the Internet access service can be controlled according to the new control strategy.

Therefore, the method for monitoring the quality of Internet access services for a mobile terminal provided by this embodiment of the present invention includes: installing GUI technology on a mobile terminal, monitoring the quality of Internet access services for a mobile terminal, collecting statistics on the QAR of Internet access services for a mobile terminal and downloading the QAP obtained using statistical data on a network server so that the network server controls the quality of Internet access services for mobile terminal according to the QA, thereby exercising precise network quality control for the mobile terminal and providing the basis for accurate decision-making on network planning and optimization by the operator. In addition, by developing a uniform control strategy on the network side, control can be made more targeted.

It should be noted that the mobile terminal mentioned in the embodiment of the present invention may be a wireless mobile terminal that provides Internet access using any wireless network technology, such as 2G, 3G or LTE (long-term development).

As mentioned above, since various types of Internet access services have different characteristics, for different types of services, statistical data can be collected according to the basic quality indicator according to the corresponding message of the type of Internet access service, which is described in detail below.

1. For the HTTP Web Resources Viewer service, messages corresponding to the events listed in Table 1 can be identified and verified.

The successful response of the HTTP start page, HTTPHomePageResponse, means that the mobile terminal received a successful response to the first connection request, the HTTPHomePageRequest, initiated by the mobile terminal.

FIG. 4 is an HTTP service messaging procedure for a mobile terminal according to an embodiment of the present invention.

Marks in the boxes are user awareness points, including:

Label A, indicating that the user has called up the start page;

Label B, indicating that the user is already accepting the response of the page;

Label C, indicating that the user clicked on the link to refresh the web page;

Label D, indicating that the user accepts the response of the updated page; and

Label E, indicating that the user is viewing the contents of the updated page.

With reference to FIG. 4 illustrates, by way of example, a process for collecting statistics on a core quality score for an HTTP service according to an embodiment of the present invention.

Example 1: It is assumed that the QoS indicator for which statistics are to be collected includes the success rate of the response of the HTTP start page and the response time of the HTTP start page.

The percentage of successful HTTP start page response attempts refers to the ratio of the successful response time of the HTTP start page to the total time that the connection to the start page was initiated; the response duration of the HTTP start page refers to the time period from the mobile terminal initiating the first connection request to the start page to receiving the response corresponding to the first connection request to the start page.

The mobile terminal raises an HTTP webpage start page connection request event, HTTPHomePageRequest; the mobile terminal initiates a connection request with the radio interface (corresponding to the awareness point A in FIG. 4), that is, an OAI connection request to the radio base station / RNC (radio network controller, RNC) to establish an OAI connection; activates the PDP context; establishes a TCP connection; and then initiates an HTTP Get request for the HTTP start page. In this case, the mobile terminal receives a 200 OK message sent by the WAP gateway or PU; and in case of failure, another value is sent.

For the POC indicator of the percentage of successful attempts to respond to the start page according to the standard protocol format, the method message corresponding to the first line is checked; if the method message is Get, this means that the user initiates one HTTP Get request, which is the start event corresponding to the first line, where “200 OK” indicates a success, which is the end event, corresponding to the Qoq of the percentage of successful attempts to respond to the HTTP start page . Another feedback status code indicates failure and cause. Statistics are collected for the start event and end event over a specific period, and according to the result of the statistics, the percentage of successful home page response attempts is calculated.

For the POK indicator of the initial page response duration, the mobile terminal can record the duration corresponding to the initial event and the final event of the share of successful attempts to respond to the initial page, and calculate the duration of the initial page response based on the average value for which statistics on the initial and final events are collected for a certain period.

Additionally, since each HTTP connection is uniquely identified by a "five" (IP / port source, IP / port final destination, and protocol), in the above verification process, the fact that the starting event or the response event includes the same connection or one the same web page can be determined according to the unique "five".

Example 2: It is assumed that the QoS indicator for which statistics are to be collected includes the percentage of successful attempts to update the HTTP page, the duration of the update of the HTTP page, and the loading speed of the HTTP page.

The percentage of successful attempts to update an HTTP page refers to the ratio of successful downloads through the mobile terminal of an entire web page to a mobile terminal; HTTP page refresh duration refers to the period from the start of downloading through the mobile terminal of the first connection of the web page to the successful receipt of the response of the last connection; and the HTTP page download speed refers to the ratio of the size of the web page downloaded through the mobile terminal to the duration of the HTTP page refresh.

The mobile terminal initiates one HTTP Get request per HTTP page; in this case, the mobile terminal receives an HTTP 200 OK message sent by the WAP gateway or PU; based on the response content, the mobile terminal determines whether to continue to send a new connection request to the page; if there is a new connection request, fires the HTTPDataTransferStart event and continues to send one or more HTTP Get requests; the mobile terminal collects statistics on the response speed of the HTTP Get request and the HTTP 200 OK message and, based on the specified threshold, determines whether the page loading was successful.

Therefore, for the QAP of the share of successful attempts to update an HTTP page, the duration of an HTTP page refresh, and the speed of an HTTP page to load, the HTTP Get request and the many responses with a 200 OK status code corresponding to the HTTP Get request should be checked in the same way. The process of checking the HTTP method and the response event is similar to the process of checking the success rate of the response of the HTTP start page and will not be described in detail again. The mobile terminal collects statistics on the ratio of the number of successful attempts to the number of page refresh initiations and calculates the percentage of successful HTTP page refresh attempts.

The duration of an HTTP page refresh is obtained by calculating the time period from the first HTTP Get event to the last HTTP response event of one HTTP page. Of course, statistics can also be collected on the duration of the refresh of the HTTP page over a certain period to obtain the average duration of the refresh of the HTTP page.

The loaded page size can be obtained by checking the content length field of the HTTP response event, and the HTTP page loading speed can be obtained by calculating the ratio of the loaded page size to the duration of the HTTP page refresh.

For example, for the QoS of the HTTP Web Resources Viewer service, suppose that the result of the statistical data of the HTTP Web Resources Viewer service for a certain period of time is shown in Table 2.

According to the entries in table 2, the corresponding QAP can be obtained by calculations as follows:

The share of successful attempts to respond to the initial page: the number of successful attempts / the number of views of web resources = 5/5 = 100%;

Duration of the initial page response: Σ total duration / number of page views = (5 + 10 + 6 + 10 + 5) / 5 = 7.2 seconds;

Page refresh duration: Σ total page refresh duration / number of page updates = (6 + 10) / 2 = 8; and

Page loading speed: Σ total web page size / Σ total web page response time = (1036 + 2046 + 2100 + 2046 + 1046) / (5 + 10 + 6 + 10 + 5) = 229 bytes / s.

2. For the WAP service, messages corresponding to the events listed in Table 3 can be identified and verified.

The WAP Internet access service data packet receives the header encapsulation in the HTTP Internet access service data packet, where the header encapsulation is removed during the verification process. The process of collecting statistics for all QAP is similar to that of the service for viewing HTTP web resources.

3. For the FTP service, messages corresponding to the events listed in Table 4 can be identified and verified.

For the FTP service, as soon as a newly established FTP “five” is detected, an FTP connection request is initiated until a “220” command is received from the server, which means that the connection was established successfully; receiving another command means rejection.

Therefore, using the time statistics of the connection initiation event and the command event sent from the server, it can be determined whether the connection is established according to the corresponding sent result. By collecting statistics on the ratio of the number of successful connections to the total number of connection initiation events, you can get the percentage of successful FTP connections.

The duration of establishing an FTP connection can be obtained using statistics on the length of time from the connection initiation event to the command event sent from the server, and collecting statistics on the average duration obtained over a period of time.

The event of the PASV message of the download service to the main system means that the mobile terminal has started to download the file, the reception of the event confirming that the “226” command was sent by the FTP server means that the file download is completed, and the other commands sent indicate failure; the duration of the time interval from the event of the download service to the main system to the event confirming that the command was sent by the server is measured; when FTP is in PORT mode, the file size contained in the “150” command is checked for a RETR request; when FTP operates in PASV mode, the file size is checked, which is contained in the response of the “213” command to the SIZE request; the ratio of file size to download time to the host system is calculated to obtain the average FTP upload speed to the host system.

The event of the PORT message of the download service from the main system means that the mobile terminal has started to download the file, the reception of the event confirming that the “226” command has been sent by the FTP server means that the file download is completed, and the other commands sent indicate failure; the duration of the time period from the download service event from the main system to the event confirming that the command was sent by the server is measured; when FTP is in PORT mode, the file size contained in the “150” command is checked for a RETR request; when FTP operates in PASV mode, the file size is checked, which is contained in the response of the “213” command to the SIZE request; the ratio of file size to download time from the host system is calculated to obtain the average FTP download speed from the host system.

4. For the DNS service, messages corresponding to the events listed in Table 5 can be identified and verified.

DNS is the standard protocol, and the major events are the DNSQuery event and the DNSResponse event, which correspond to the Request field and the Response field of the DNS message, respectively; if the "DNS query" field is checked in "", then it is determined that the DNS check is successful. Therefore, the ratio of the number of successful DNS verification attempts to the number of queries over a period of time is measured to obtain the percentage of successful DNS verification attempts. Time points corresponding to each DNSQuery event and DNSResponse event are recorded to obtain the duration of the DNS check; The average DNS check duration over a period of time is measured to obtain the DNS check delay.

5. For the TCP service, messages corresponding to the events listed in Table 6 can be identified and verified.

The standard TCP protocol establishes a connection using a three-way presentation protocol; Establishing a connection using the standard TCP protocol includes three events: TCPSYNAttempt, TCPSYNACK, and TCP_ASK.
